Okobi was sentenced to pay a $100 fine. A district judge threw out all of Okobi's other charges after hearing testimony at a preliminary hearing last year.

Defense attorney Robert Del Greco has said that Okobi acted in self-defense and was not the first person to take a swing in the Aug. 25 altercation at Bar Room.

"Blair Ferguson started the fight, by all accounts. He was found guilty of that, and the charge relative to my client was dismissed," Del Greco said after last year's preliminary hearing. "He was essentially jumped at the bar. At one point, five people were on top of him and he was on the bottom. He was beat up."

Ferguson was found guilty of simple assault, and the judge ordered Okobi to stand trial on one count of simple assault related to bar security guard Joe Kania. That charge was the one that prosecutors dropped in exchange for Okobi's harassment plea Monday.

"I think he held over on the security guard because of his status, and I think the judge's opinion was that, in Chukki's efforts to defend himself, that he might have been excessive," Del Greco said last year. "That's not our opinion, when pounced on by more than one person. And we have bear hugs, we have punching, we have shoving. People react a certain way, and it's our opinion that he defended himself correctly, and we intend to challenge that case."

Okobi, 33, was a fifth-round draft pick by the Steelers in 2001 and played for them until 2007. More recently, he has been a rapper under the name Chuk Wun and became known for the various "Buc Town" songs about the Pittsburgh Pirates.
